Filed: 1946-08-14
Abstract: 650,871. Automatic control systems for aircraft cabins. BOEING AIRPLANE CO. Aug. 14, 1946, No. 24194. Convention date, Aug. 17, 1945. [Class 38 (iv)] [Also in Group XXIX] A control unit for an aircraft cabin pressure regulator comprises a pattern member, the pattern of which corresponds to the desired altitude cabin-pressure characteristic, and an associated pattern tracing member, the relative disposition of the two members being determined by the ambient atmospheric pressure and being effective to control the cabin pressure regulation. A valve 1, Fig. 1, controlling the outflow of air from a pressurized cabin through a filter 12 to the atmosphere is actuated by a diaphragm 15. The space below the diaphragm is in unrestricted communication through a port 16 and a passage 17 with the cabin, and the space above the diaphragm is connected through a throttling valve 19 to the cabin and through a central passage 14 in the outflow valve 1 to the atmosphere. The outflow of air from the upper space and thus the position of the diaphragm is controlled by a spring-loaded valve 20 actuated by a leaky piston 21 subjected on its lower face to cabin pressure, and on its upper face to the pressure in a pipe 2 connected to the control unit 3, which is provided with a leak-off valve controlling the communication between the pipe 2 and a pipe 30 leading to the atmosphere. The control unit may contain a pattern screen positioned by an evacuated bellows actuated by the ambient atmospheric pressure, and an associated photo-electric cell tracing member positioned by a bellows actuated by the pressure difference between the cabin and atmospheric pressures. The screen is interposed between a light and the photo-electric cell tracing member, which is connected in a circuit controlling the electrical actuation of the leak-off valve. Specifications 521,623 and 577,349, [both in Group XXIX], are referred to.

Title: Improvements relating to presses for consolidating finely divided materials
IPC: B30B15/00
Filed: 1950-10-13
Abstract: 693,450. Compression - moulding machines. CLARK, F. H., and LEES, C. A. Oct. 15, 1951 [Oct. 13, 1950], No. 25006/50. Addition to 669,835. Class 87 (ii). The parent Specification describes a press for consolidating finely-divided material in a mould the air being removed from the material by vacuum before it is consolidated by pressure. It has been found that when the mould is put under vacuum there is a tendency for the bottom die (the article-ejector) to be sucked upwards, and the present invention seeks to remedy this by holding the die down. The die is secured to the upper end of a vertical plunger a, and this plunger is held down, during the application of the vacuum, by two hooks r which engage rollers q mounted in lugs p secured to the plunger. The hooks are mounted on fixed pivots t and are pulled together by a spring (not shown) engaged in holes v in the hooks. When the consolidation has been effected and the moulded article is to be ejected, a manually-operated lever (not shown) engaging in a slot k in a sleeve j is raised, whereby chamfered edges x on the upper end of the sleeve engage rollers w on the hooks and cam them aside, the hooks being thus moved aside off the rollers q and a spring n urging the plunger a upwardly to eject the article. The retaining edges y of the hooks are struck from centres z displaced inwardly from the centres of the pivots t, so that as the hooks move inwardly they pull down on the rollers q to seal the bottom of the mould. An extension e of the plunger has a pin l which moves in a slot m in the fixed support s on which the hooks are pivoted. If the rollers q are to rise above the hooks, the upper ends of the hooks may have rollers by which the hooks may be moved apart by descent of rollers g.

Title: Improvements in or relating to the manufacture of sodium perborate
Inventor: WOOD WILLIAM STANLEY
IPC: C01B15/12
Filed: 1953-09-17
Abstract: Sodium perborate is prepared by mixing anhydrous sodium tetraborate or an impure mineral sodium borate or boric acid with a sodium hydroxide solution, if necessary with heating, to form a solution containing 300-1000gm/l. of sodium metalborate at a temperature (e.g. 30-95 DEG C.) which prevents it from crystallizing, if necessary filtering this solution, and then reacting it with or without dilution with a sodium peroxide or hydrogen peroxide solution.  It is preferred to employ a cyclic process in which the sodium hydroxide is present in a mother liquor from a previous precipitation, and after removing precipitated perborate the whole or a part of the residual liquor is recycled.  If desired the hot concentrated metaborate solution and the peroxide solution may be run simultaneously into water or a mother liquor from a previous process, when a portion of mother liquor is not recycled, as when using a dilute hydrogen peroxide solution, e.g. 4 per cent w/w, it may be treated with sodium chloride to salt out additional product.  In examples, temperatures were maintained at 25 DEG C. and magnesium sulphate added as a stabilizer during the addition of hydrogen peroxide.
